Scientists Have Solved a Decades-Old Mystery About Polar Bears

If there are no woods where they live, where do they…

Scientists have long wondered whether polar bears are able to enter a physiological state resembling hibernation in response to food shortages, an adaptation some researchers have speculated could protect the species even as their hunting grounds melt away. Today, we have an answer—though it’s not the one we’ve been hoping for.

The bears were outfitted with fitness trackers 😉

Hibernating Hints at Dementia Therapy

Bears, hedgehogs and mice destroy brain connections as they enter hibernation, and repair them as they wake up.

A UK team discovered “cold-shock chemicals” that trigger the process. They used these to prevent brain cells dying in animals, and say that restoring lost memories may eventually be possible.

We know that RBM3 protects, regardless of whether it was produced by hibernation or artificial elevation of just the protein RBM3.  So you don’t need to go out trying to freeze yourself 😉
